Assertion : Current is passed through a ...

Assertion : Current is passed through a metallic wire, heating it red. Half of its portion is cooled by cold water jacket, then rest of the half portion become more hot.
Reason: Resistances decreases due to decrease in temperature and so current through wire increases.

A

If both Assertion `&` Reason are True `&` the Reason is a correct explanantion of the Assertion

B

If both Assertion `&` Reason True but Reason is not a correct explanation of the Assertion

C

If Assertion is True but the Reason is False

D
